MERN Stack & Tutor at Dectac

As an experienced MERN Stack developer and tutor, I bring over 6 years of hands-on expertise in both frontend and backend development. On the frontend, I have mastered React.js, allowing me to build dynamic and scalable user interfaces that provide seamless experiences across devices. On the backend, I specialize in Node.js, crafting robust server-side applications that integrate seamlessly with databases, handle high traffic, and leverage AI tools for enhanced performance. My goal is to equip you with the knowledge and confidence to apply these skills in real-world projects.

Build like a beginner, deploy like a pro, scale like a leader — that’s the Dectac way.

At Dectac, we didn’t just build a MERN Stack course — we crafted a real-world pathway for full-stack development success. With years of experience building scalable web applications, working with client projects, and delivering enterprise-level solutions, we saw the gap between theory and real-world application — and we’re here to close it. Our mission? To shape confident, job-ready full-stack developers through hands-on practice, integrated AI tools, collaborative project work, and mastery of industry-standard technologies. Whether you’re a fresher or a career switcher, we’re committed to helping you not just learn the MERN stack — but truly master it.
